Question

the product of two consecutive numbers is 210 . can you tell the number​

Answer 1

let the consecutive number be X and X + 1

X×(X+1)=210

square of x + x-210=0

square of x+15x-14x-210=0

x(x+15)-14(x+15)=0

(x-14)(x+15)=0

x=14 or x=-15

I think this is helpful to you

thank you

Answer 2

Answer:

The numbers are 14 and 15

Step-by-step explanation:

Let one number be x .

Then other number is x + 1.

x ( x + 1 )     = 210

x² + x          = 210

x² + x - 210 = 0

x² + 15x - 14x - 210 = 0

x ( x + 15 ) - 14 ( x +  15 ) = 0

(x + 15) ( x - 14) = 0

x = -15 , x = 14
